DAVID B. CAMPBELL, OF BUTLER, PENNSYLVANIA.

BULL-'WHEEL FOR OIL-VTELL CABLES.

Application filed February 18, 1914.

To all whom it Til 66]] concern:

Be it known that 1, DAVID B. CAMPBELL, a citizen of the United States of America, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Bull-Wheels for Oil-Nell Cables, of which. the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to bull wheels for oil well cables, and has for its object to provide a wheel of such class, formed of separable sections whereby when one section becomes damaged, it may be removed, one substituted, and under such conditions overcome the necessity of throwing away the entire wheel when. a portion thereof becomes damaged, as is the case at present when any portion of the wheel becomes injured.

Further objects of the invention are to provide a bull wheel for oil well cables which is simple in its construction and arrangement, strong, durable, eflicient and convenient in its use, readily set up and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more fully described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings wherein like reference characters denote corresponding parts throughout the several views, and in which Figure l is an elevation of a bull wheel in accordance with this invention; Fig. 2 is a longitudinal section view; and Fig. 3 an end View.

The hull wheel includes a pair of heads and each of which includes a body portion formed of a pair of semicircular members l5, which abut to provide an annulus. Arranged against the inner face of the body portion of each head is a series of radially disposed flat tapering spokes 7, and arranged against the outer face of the body portion of each head is a series of radially disposed fiat tapering outer spokes S. The inner spokes are arranged parallel to the Specification of Letters Patent.

Serial No. 819,543.

outer spokes, and arranged between the inner and outer spokes are pairs of sleeves 9 which in connection with the body portion maintain the spokes in space relation, and furthermore constitute a bracing means between the inner and outer spokes. The inner and outer spokes are connected to the body portion by bolts 1.0 and 11. The bolts 11 are arranged between the bolts 10 and are of greater length than said bolts 10. The bolts ll project inwardly from one head and outwirdly from the other head, and carry sleeves 12 which abut against the heads of said bolts. The bolts 11 of one head have their sleeves 1) abutting against the inner spokes of said head, while the bolts 11 of the other head have their sleeves 12 abutting against the outer spokes of their respective head. The bolts 11 carry nuts 13 whereby the said bolts are detachably secured in position. The bolts 10 carry nuts let whereby said bolts are detac-hably secured in position. Arranged against the inner spokes are radially disposed members 15 which are secured in position by bolts 16, these latter extending through the members 15, having their heads 17 mounted snug in said members 15., and further extending through the inner and outer spokes, as well as the sleeves 9, and carry nuts 18 which engage the outer spokes whereby said bolts 16 are detachably secured in position. The bull wheel further includes a hub formed of a hollow cylindrical inner section 19 which abuts against the inner spokes, a pair of hollow cylindrical outer sections 20-21 which abut against the outer spokes, and apair of collars 22- 23 of the same diameter as the sections 19- 2021, and said collars are positioned in the heads of the wheels between the inner and outer spokes of the heads. further includes a pair of disks 2 l25, which are arranged within the section 19 of each end thereof and abut against the inner ends of the inner spokes. Each of the sections 20 21 has its inner face formed with threads 26 with which detachably engages the peripherally threaded head 27 of a journal 28. Each of the heads 27 is formed with an annular flange 29, and the said flanges 29 abut against the sections 20 9.1. The hub further includes a series of detachable stay members, and each of said members consists of a longitudinally extending rod 30, provided at each end with The hub peripheral threads 31. The rods 30 are arranged within the sections l92021, extend through the marginal portion of the disks 2%25, further extend through the inner ends of the inner and outer spokes and project throughthe heads 27. lvlounted upon the threaded ends 31 of the rods 30 are nuts 32 which engage the heads 27. The body portion of one of the heads is peripherally grooved as at 33.

From the foregoing construction and arrangement of parts, it is obvious that a knock-down construction of bull wheel is provided, and which enables the removal of a damaged part of a wheel and a new one substituted without discarding the wheel as an entirety.

WVhat I claim is 1. A. bull wheel comprising a pair of heads, each consisting of a detachable body portion and detachable inner and outer spokes, a hub formed of a series of detachable sections and tie members, said tie members extending through the inner ends of said spokes for connecting the heads to the hub.

2. A bull wheel comprising a pair of heads, each consisting of a detachable body portion and detachable inner and outer spokes, a hub formed of a series of detachable sections and tie members, aid tie members extending through the inner ends of said spokes for connecting the heads to the hub, and each of said heads provided with bracing means interposed between the inner and outer spokes of the head.

3. A bull wheel comprising a pair of heads, each consisting of a detachable body portion and detachable inner and outer spokes, a hub formed of a series of detachable sections and tie members, said tie members extending through the inner ends of said spokes for connecting the heads to the hub, and a pair of heads engaging with said hub, and further connected to the hub by said stay members and provided with journals.

4. A bull wheel comprising a pair of ieads, each consisting of a detachable body portion and detachable inner and outer spokes, a hub formed of a series of detach able sections and tie members, said tie members extending through the inner ends of said spokes for connecting the heads to the hub, and each of said heads provided with bracing means interposed between the inner and outer spokes of the head, a pair of heads detachably engaging with said hub and further connected to the hub by said stay members, and provided with journals.

5. A bull wheel comprising a pair of ieads, each consisting of a detachable body portion and detachable inner and outer spokes, a hub formed of a series of detachable sections and tie members, said tie members extending through the inner ends of said spokes for connecting the heads to the hub, and a pair of heads detachably connected to said hub and provided with journals.

6. A bull wheel comprising a hub, a pair of ournals and a pair of heads, each of said heads including a body portion, an inner and outer set of radially disposed flat spokes, means for detachably connecting the sets of each head together, means for detachably connecting the sets of each head to the body portion, said hub including a series of detachable sections and further including stay members extending through the spokes for connecting them to the head, and said stay members further constituting means for connecting the journals to the hub.

7. A bull wheel comprising a hub, a pair of journals and a pair of heads, each of said heads including a body portion, an inner and outer set of radially disposed fiat spokes. means for detachably connecting the sets of each head together, means for detachably connecting the sets of each head to the body portion, said hub including a series of detachable sections and further including stay members extending through the spokes for connecting them to the head, said stay members further constituting means for connecting the ournals to the hub, and bracing means interposed between the sets of spokes of each head.

In testimony whereof I afiix my signature in the presence of two witnesses.
